Just over a year ago, in June 2014, various details emerged of Microsoft's upcoming Windows Phone plans, and among the various tidbits revealed were two codenames of future devices. These two handsets were said to be new flagships: a large high-end device, known as 'Talkman'; and an even larger phablet, referred to as 'Cityman'.

Microsoft has focused on entry-level devices in recent months, like the Lumia 640

One of the two handsets - tracked by its model numbers, RM-1104 and RM-1105 - had a 5.2-inch 1080p display, which corresponds with what's previously been reported about Talkman. The second device, RM-1100, had a display of unknown size, but with Quad HD (2560x1440px) resolution; this device is believed to be Cityman.

That Quad HD display lines up with the unconfirmed specs revealed last month for the device. Key specs of the handset are said to include:

5.7-inch QHD display

Octa-core Qualcomm processor

3GB RAM

32GB storage (plus microSD card slot)

20MP rear camera

5MP front-facing camera

3300mAh battery

USB Type-C connector

Windows Central reports today that it has 'confirmed' via its sources that these specs are accurate, and adds that Cityman's camera will also have a triple-LED flash.

Both Talkman and Cityman are expected to be launched in the last quarter of 2015 - around October or November - shortly after Microsoft finalizes its RTM build of Windows 10 Mobile in September. Those codenames will, of course, be dropped for production - the handsets are widely expected to be known as the Lumia 940 and Lumia 940 XL when they go on sale.
